MORTIMER A. OLAPP, OF AUBURN, NEW' YORK, 'ASSIGNOR TO D. M. OSBORNE 8: COMPANY, OF SAME PLACE.

HARVESTER-REEL.

SPECIFICATION forming part of Letters Patent No. 377,372, dated February '7, 1888.

Application filed December 4, 1886.

To all whom it may concern:

Be it known that l, MORTIMER A. GLAPP, of Auburn, in the county of Cayuga and State of New York, have invented certain Improvements in Reels for Harvesters, of which the following is a specification.

My invention has reference to that class of reel mechanisms in which a horizontal rockshaft is provided with a crank-arm carrying the bearings of the horizontal reel-shaft, so that the turning motion of the rock-shaft will have the effect of raising and lowering the reel.

The particular aim of the invention is to simplify the mechanism for operating the rockshaft, to give the operator convenient control of the reel in its various operative positions, and to admit of the reel being thrown inward or rearward from its operative position to re duce the space occupied by the machine and to facilitate its storage or transportation.

Referring to the accompanying drawings, Figure 1 represents a side elevation of the reel-supporting mechanism constructed on my plan. Fig. 2 is a front elevation of the same. Figs. 3, 4, and 5 are diagrams illustrating the principal positions of the parts.

In the drawings, A A represent two bearings fixed to standards or other suitable supports, and containing the horizontal rock-shaft B, the overhanging end of which is fashioned into or provided with a crank-arm carrying at its outer end bearings O of any suitable character, in which the horizontal reel-shaft D is mounted, the reel being of the usual overhung type. The crank-arm is extended a sufficient distance to receive one or more reel-shaft bearings, O, which will be secured rigidly thereon by set-screws or their equivalents. These details may be of any ordinary construction, as they constitute no part of my invention, and are now known in the art in various forms. It will be perceived that the shaft B thus arranged serves to support the reel-shaft, and that when revolved in its bearings A the crank- 5 arm, sweeping through the vertical path, will have the effect ofraising and lowering the reelshaft. To the rock-shaft B, I fix firmly a laterallyprojecting arm, E. To a bracket-plate, F, or other rigid support, I pivot ahand-lever,

G, connecting the same at a suitable point in Serial No. 220,671. (No model.)

its length by a link, H, to the arm E of the rock-shaft..

I provide the hand-lever with a sliding catch or dog, I, controlled by a thumb-lever, J, and arranged to engage in stationary locking-teeth K, which may be formed on the rear edge of the bracket F, as shown, or otherwise. The locking-dog, as shown, is of a form familiarto those skilled in the art, and it may be replaced by any other equivalent locking device which will serve to hold the hand-lever in its different positions. When the reel is in operative position, its shaft stands in front of a vertical line passing through the shaft B.

In Figs. 1 and 3 the reel is shown in iislowest operative position, its shaftstanding almost directly under the rockshaft B and the handlever standing in its highest position. On depressing the lever the link H, acting through the arm E,will turn the rock-shaft B, and thus carry the crank-arm and reelshaft upward until they assume their highest operative positions. (Representedin Fig. 4.) Bylocking the hand-lever at suitable points the reel may be sustained at any desired elevation between the extremes represented in Figs. 3 and 4.

WVhen it is desired to throw the reel rearward beyond its ordinary position, it is first lowered in a forward direction by elevating the lever and then thrown sharply upward by 8c a sudden depression of the lever, care being taken to give itsuch momentum that the crankarm will be carried upward and rearward past the center, or, in other words, past the vertical line falling through the shaft D,wherenpon the elevation of thelever, owing to the changed relation of the parts, will permit the reel to descend to the position indicated by full lines in Fig. 5. It will be observed that when thus adjusted the reel stands in rear of its ordinary 9c operative position. It may be carried forward and returned to its operative position by sharply depressing the lever, so as to throw the crank forward over the center.

It will be perceived that the reel-sustaining crank and the eontrollingarm E project from the shaft in directions which are almost diametrically opposite, and that the various parts are so arranged that the crank B may make nearly an entire revolution. I These facts are of importance, in that they permit the crank to be swung through a very long are by the lever,and that' they permit the parts to assume such relative positions that the reel may be given sufficient momentum to throw it over the center with certainty.

I am aware that a vibratory frame supporting the reel has been provided with an arm extending at right angles thereto and connected by a link to a hand-lever, the organization being such that the lever would serve to vibrate the frame through a short are in a vertical direction; but I believe myself to be the first to so arrange the parts that the reel can be practically thrown rearward beyond the axis of its sustaining-crank and beyond its operativeposition at .will.

The essence of myinvention resides in proriding the rocking crank-shaft which carries the reel with a hand-lever with devices which admit of the crank being thrown forward and backward of its axis, and it is manifest that the details of construction may be modified at will within therange of mechanical skill with out departing from my invention.

Having thus described my invention, what I claim is- 1. In a harvester, the horizontal rock-shaft mounted in fixed bearings and having the overhung cranked end, in combination with the reel-shaft carried by said cranked end, an arm, E, secured rigidly to the rock-shaft and extending therefrom in an opposite direction from the crank, a hand-lever, G, pivoted to being thrown downward and rearward in relation to the rockshaft, as described.

2. In a harvester, the horizontal rockshaft B, having the cranked end, the stationary bearings for said shaft, the horizontal reel-- shaft carried by the crank arm of the rockshaft, the arm E, fixed to the rock-shaft and I extended in opposition to the crank, the stationary toothed plate F, the hand-lever G,

pivoted to said plate below the rock-shaft, a link, H, connecting said leverwith the arm E, as described and shown, and thelocking-dog I, to hold the lever in diii'erent positions, said parts constructed and arranged as described, whereby the reel may be adjusted and fixed at different heights in advance of the rock-shaft foraction or folded downward in rear of the rock-shaft for transportation.

In testimony whereof I hereunto set, my

hand, this 9th day of November, 1886, in the presence .of two attesting witnesses.
